I am interested in testing the functionalities of virtual access points. After reading all the available documentation on the sites and in the source code I managed to create some and to get different mobile nodes to successfully connect to them.
Anyway I was interested in testing the technology under a heavy load (with like more than 10 VAPs at least) and I am getting an error while trying to create more than 3 virtual ap.
They are all created in ap mode, and after the third one (named ath2) I got an ioctl: input/output error.
I read in the doc that the limit should be 32 or 64, so anybody got ideas of why this is happening?
I am running ubuntu 8.10 with default package drivers. The card is an Atheros AR5001X+.
The command I use is wlanconfig ath create wlandev wifi0 wlanmode ap.
Thank you all!
